چکیده
|
The skewed and weighted distributions may be considered as nice alternatives to fit a real data set in practical situations in which the well-known distributions are not suitable. the weighted distributions are first discussed and then two extensions of weighted models are proposed in this paper to analyze the skew data. the flexibility of the models is studied in view of the moment skewness coefficient for some cases. finally, two real data sets are used to illustrate the results of the paper.
